INTRODUCTIONMany systemic conditions have oral manifestations. Recognition of these clinical signs may facilitate early diagnosis or in some cases provide some understanding of the level of control of the disease.
Systemic disorders may signal their presence by oral symptoms. Such as :- • Gums that have grown over the teeth may mean a patient has leukemia. • A red or furry tongue may indicate scarlet fever.• A tongue covered with brownish sores, typhoid fever.• A pale, smooth glossy tongue, pernicious anemia. • A fine black line that appears on the gums,chronic lead poisoning.• Spongy gums signal chronic mercury poisoning.

A doctor can also find diagnostic clues to Addison's disease Diabetes mellitus Vitamin B deficiency Scurvy Sjogren's syndrome (an autoimmune disorder ) Inflammatory bowel disease Multiple sclerosis by examining the oral cavity. Foul breath may indicate a lung abscess. An extended tongue that bends to one side may indicate a stroke.
Thus the mouth is a valuable reflection of what's going on in our body.

It is a condition in humans in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive.
Infection with HIV occurs by the transfer of body fluids.
Within these bodily fluids, HIV is present as both free virus particles and virus within infected immune cells.

Reddenning of the oral mucosa, followed by numerous small vesicles formation over the keratinised mucosa. E.g.- gingiva, palate, lips, etc
The vesicles contain clear fluid & rupture to leave multiple small, shallow painful ulcers.
These are followed by diffuse
large whitish ulcers surrounded by a red ring of inflammation(halo).

EPSTEIN-BARR VIRUS• The most common disease associated with Epstein-Barr virus (EBV) is infectious mononucleosis, also called mono or "kissing disease."
• Symptoms include fever, fatigue, enlarged glands and sore throat.
• The virus is in saliva and moves easily from person to person by the exchange of saliva.
• Epstein-Barr virus infection may also cause a mouth sore (lesion or patch) called hairy leukoplakia, which looks white. It usually shows up on the side of the tongue.
• Epstein-Barr virus has also been associated with cancer of the upper part of the throat.

HUMAN PAPILLOMA VIRUS
Modes of Transmission for Oral HumanPapilloma Virus: HPV is transmitted by skin-to-skin contact, not via exchange ofbodily fluids.
Symptoms of Oral Human Papilloma Virus: Most often HPV warts appear on the lips, but they can also appear on the tongue, gums, throat and palate. Lesions are more likely to be experienced by people with compromised immune systems.
Treatment for Oral Human Papilloma Virus: There is no known cure. Warts can be suppressed by chemicals, freezing, laser therapy and surgery. Unfortunately, effective antiviral drugs for HPV have not been developed yet.

ORAL MANIFESTATIONS
PRIMARY SYPHILIS of the mouth manifests as a solitary ulcer usually of the lip or, more rarely, the tongue. The ulceration is usually deep, with a red, purple, or brown base and an irregular raised border.
SECONDARY SYPHILISMaculopapular lesions1. Macular syphilides: Macular lesions arise on the hard palate and manifest as flat-to-slightly raised, firm, red lesions.2. Papular syphilides: They manifest as red, raised, firm round nodules with a grey center that may ulcerate. 3. Mucous patches: These manifest as oval-to-crescenteric erosions or shallow ulcers of about 1 cm diameter, covered by a grey mucoid exudate and with an erythematous border.
![Page 36: Oral Cavity is the Mirror of Your Own Body](https://reader035.vdocuments.us/reader035/viewer/2022062618/54faec044a7959f0388b4668/html5/thumbnails/36.jpg)
TERTIARY SYPHILISClinical disease arises in about one third of patients with untreated secondary syphilis. The oral complications show gumma formation,syphilitic leukoplakia (and risk of oral squamous cell carcinoma) and neurosyphilis. GUMMA FORMATIONGummas tend to arise on the hard palate and tongue, A gumma manifests initially as 1 or more painless swelling.The swellings eventually develop into areas of ulceration, with areas of breakdown and healing. There may be eventual bone destruction, palatal perforation, and oro-nasal fistula formation.

HORMONAL DISORDERSDIABETES MELLITUS
It is a group of metabolic diseases in which a person has high blood sugar, either because the body does not produce enough insulin, or because cells do not respond to the insulin that is produced.
This high blood sugar produces the classical symptoms of polyuria (frequent urination), polydipsia (increased thirst) and polyphagia (increased hunger).
![Page 38: Oral Cavity is the Mirror of Your Own Body](https://reader035.vdocuments.us/reader035/viewer/2022062618/54faec044a7959f0388b4668/html5/thumbnails/38.jpg)
ORAL MANIFESTATIONS OF DIABETES MELLITUS
1.PERIODONTAL DISEASE Microangiopathy altering antigenic challenge Altered cell mediated immune response &
impaired neutrophil chemotaxis. Increased Ca+ & glucose lead to plaque
formation. Increased collagen breakdown.
2.SALIVARY GLANDS Xerostomia is common. Tenderness, pain & burning sensation of tongue.
![Page 39: Oral Cavity is the Mirror of Your Own Body](https://reader035.vdocuments.us/reader035/viewer/2022062618/54faec044a7959f0388b4668/html5/thumbnails/39.jpg)
3. DENTAL CARIESIncreased caries prevelance in adult with diabetes.(xerostomia, increased salivary glucose).
4. ORAL BURNING & TASTE DISTURBANCES
The burning may be due to peripheral neuropathy, xerostomia or candidiasis.
Good glycemic control may alleviate the burning sensation.
Some patients have mild impairment of sweet taste sensation. This may be due to disordered glucose receptors or xerostomia.
